Description of problem:
I beleive the same problem occurs with kernel-source-2.4.18-27.8.0, aswell.

Compiling my company's driver against the redhat kernel (as opposed to the 
kernel 2.4.18) caused a subtle behavour change in the driver.

I have tracked the problem down to the kernel define "HZ" being set to '512' as 
opposed to being '100' as in the kernel.org kernel.

Version-Release number of selected component (if applicable):
kernel-source-2.4.18-14

How reproducible:
Always

Steps to Reproduce:
1. create minimal driver to prink out value of HZ
2. compile and load driver for stock redhat 8 kernel
3. compile and load driver for kernel.org 2.4.18 kernel
4. compare results
    

Actual Results:  the kernel define "HZ" being set to '512'....

Expected Results:  ...as opposed to being '100' as in the kernel.org kernel.

Additional info:

I'm not sure if this is a bug or intentional.
